Nonlinear spin and orbital Rashba-Edelstein effects induced by a femtosecond laser pulse: Simulations for Au(001)
Oliver Busch, Franziska Ziolkowski, Börge Göbel +2
Rashba-type spin-orbit coupling gives rise to distinctive surface and interface phenomena, such as spin-momentum locking and spin splitting. In nonequilibrium settings, one of the…
Ultrafast Orbital Hall Effect in Metallic Nanoribbons
Oliver Busch, Franziska Ziolkowski, Börge Göbel +2
The orbital Hall effect can generate currents of angular momentum more efficiently than the spin Hall effect in most metals. However, so far, it has only been understood as a stead…
Ultrafast Dynamics of Orbital Angular Momentum of Electrons Induced by Femtosecond Laser Pulses: Generation and Transfer Across Interfaces
Oliver Busch, Franziska Ziolkowski, Ingrid Mertig +1
The orbital angular momenta (OAM) of electrons play an increasingly important role in ultrafast electron and magnetization dynamics. In this theoretical study, we investigate the e…
Ultrafast dynamics of electrons excited by femtosecond laser pulses: spin polarization and spin-polarized currents
Oliver Busch, Franziska Ziolkowski, Ingrid Mertig +1
Laser radiation incident on a ferromagnetic sample produces excited electrons and currents whose spin polarization must not be aligned with the magnetization -- an effect due to sp…
Non-trivial topological valence bands of common diamond and zinc-blende semiconductors
Tomáš Rauch, Victor A. Rogalev, Maximilian Bauernfeind +11
The diamond and zinc-blende semiconductors are well-known and have been widely studied for decades. Yet, their electronic structure still surprises with unexpected topological prop…
Spin-dependent transport in a multiferroic tunnel junction: Theory for Co/PbTiO/Co
Vladislav S. Borisov, Sergey Ostanin, Steven Achilles +2
Spin-dependent electronic transport through multiferroic Co/PbTiO/Co tunnel junctions is studied theoretically. Conductances calculated within the Landauer-Büttiker formalism…
